From 0e72078128229bf9efb542e396ab44bf91b91340 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Thu, 17 Dec 2020 16:38:03 +0100 Subject: iotests: Fix _send_qemu_cmd with bash 5.1 With bash 5.1, the output of the following script changes: a=("double space") a=${a[@]:0:1} echo "$a" from "double space" to "double space", i.e. all white space is preserved as-is. This is probably what we actually want here (judging from the "...to accommodate pathnames with spaces" comment), but before 5.1, we would have to quote the ${} slice to get the same behavior. In any case, without quoting, the reference output of many iotests is different between bash 5.1 and pre-5.1, which is not very good. The output of 5.1 is what we want, so whatever we do to get pre-5.1 to the same result, it means we have to fix the reference output of basically all tests that invoke _send_qemu_cmd (except the ones that only use single spaces in the commands they invoke). Instead of quoting the ${} slice (cmd="${$@: 1:...}"), we can also just not use array slicing and replace the whole thing with a simple "cmd=$1; shift", which works because all callers quote the whole $cmd argument anyway.
